The only ‘in production’ analog synth that has more voices that I can think of and is cheaper than the analog keys is the deepmind 12. There are others cheaper that also have 4 voices, i.e. minilogue. no other synth offers so many features at the price point of analog keys currently. Thats why I bought one over other options. When getting into 6, 8 12 voice analog, starting to look at the 2K mark +, such as DSI offerings.
